    First Mini-ITX motherboard for Raspberry Pi has 11 PCIe slots

    Posted: 24 Nov 2021 08:40 AM PST

    Alftel just released their new 'Seaberry' board, a Mini ITX-sized motherboard that uses the Raspberry Pi Compute Module 4 to drive 11 PCIe slots (4x mini PCI, 4x M.2 E-key, 1x M.2 M-key, 1x x16, 1x x1)—but all through one single PCIe Gen 2 lane, meaning all that connectivity is pretty bottlenecked through the Pi's 5 Gbps of bandwidth.

    But it is a neat board, it has triple redundant 12V power supplies (though no 24-pin ATX connector), a decent amount of IO options, and the biggest downside is the cost ($435).

    Some other ITX and ATX motherboards have been announced, but none are shipping yet—and it looks like the Seaberry's already out of stock.

    To be clear, this thing isn't a replacement for a standard PC, and it will cost more than something faster/better. But it's interesting to see the first Raspberry Pi-in-a-box in an actual standard PC form factor!

    See pictures and more in my blog post on it: Mini-ITX Seaberry adds 11 PCIe slots to a Raspberry Pi. Not trying to blogspam, just honestly wanted to show that there are starting to be more non-X86 motherboards out there (like Honeycomb and someday hopefully some RISC-V-based boards).

    My expectations for Ryzen 3D V-Cache performance (based on Milan-X VCache)

    Posted: 23 Nov 2021 08:51 AM PST

    Based on information from AMD, I have collected some thoughts on where the Ryzen 3D VCache may land up in terms of expected performance.

    First, AMD's official claim is 15% gaming perf uplift vs Zen3 at 4.0Ghz fixed frequency. The fixed frequency is important, as will become clear from the bit of data.

    Second, Milan-X, which is a Milan CPU with 3D VCache added on top has been officially announced. What is interesting is that if you look closely at the clock freqs, you can easily see that Milan-X loses frequency in both Boost/Base clocks vs the Milan counterpart. This is because of 2 reasons (my hypothesis):

    1. Cache is not free from power perspective. It eats away some TDP that would otherwise be available to the cores
    2. It becomes slightly harder to cool the base die. With the 3d cache sitting on top, it's harder to wick away the heat from the cores and you can get temp limited more quickly than without the 3D cache.

    Here are the losses in Base/Boost clock frequencies for the top bins for various core counts at the same respective TDPs

    64C: -10.2% / 0% / 280W

    32C: -5% / -10% / 280W

    24C: -12.5% / -7.5% / 240W

    16C: -13% / -5% /240W

    As can be clearly seen, AMD had to sacrifice clock speed even for their flagship server CPUs with the addition of the VCache, and there's no doubt that the same will happen for Ryzen consumer CPUs as well. The average base clock reduction is about 10%, while the boost clock loses about 7.5% on average. This means that out of the 15% IPC gains that AMD projected at constant frequency, we will likely lose about half of them from clock frequency regressions.

    AMD is well aware of this and I think the small boost in performance is not worth the large increase in cost in the consumer market. Just wanted to throw this out for all the folks who are waiting for Zen 3D and be prepared for a 5-7% overall gaming uplift.

    How budget GPUs manage to keep-up with old flagships?

    Posted: 23 Nov 2021 09:24 AM PST

    Take GTX680 and 1050Ti as an example. On paper, the 680 has 2x the shader performance (1,536 vs. 768 cores) and vRAM bandwidth (192GB/s vs. 112GB/s) yet they both perform almost equally as per Hardware Unboxed (Link) . Also, the old Kepler beast has a lot more texture units (128 vs. 48). The only advantage 1050Ti really has is pixel rate, as it clocks 'much' higher, and of course it consumes almost 3x less power.

    So, how is it even possible? Is it due to the pixel rate? And what about the vRAM bandwidth? How the 1050Ti is able to load textures and vectors as fast as the 680, despite having half the bandwidth?

    It's just bugging me a lot lately so any input would be appreciated!
